This procedure contains information and instructions to keep the MBU in good working order by
inspecting and replacing the entire fuel line assembly, consisting of two compression fittings, an elbow
fitting, the fuel line, a union w/nut, and a locking nut .
Two Person Lift
The MBU weighs approximately 58 pounds fully fueled (26.3 kg). Two persons must carry the
MBU when fully fueled, lifting with legs, not back, to prevent injury.
Inspect the fuel line assembly for damage to the fuel line, and fittings. Check for leaks, loose connections
or a dented fuel line. Dents or kinks in the fuel line can restrict or prevent proper fuel flow.
Fire / Fuel Contamination
Before proceeding with this procedure, the MBU fuel tank must be drained completely as
described in work package 0011. Have rags on hand to clean up fuel spillage that may occur
to prevent contamination. Do not perform this procedure near an open flame to prevent fire.
